Description

There is a possible ReDoS vulnerability in Action Controller's HTTP Token authentication. This vulnerability has been assigned the CVE identifier CVE-2024-47887.

Impact

For applications using HTTP Token authentication via authenticate_or_request_with_http_token or similar, a carefully crafted header may cause header parsing to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade or apply the relevant patch immediately.

Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected.

Releases

The fixed releases are available at the normal locations.

Workarounds

Users on Ruby 3.2 are unaffected by this issue.
